Tryptophan fluorescence enables earlier cataract diagnosis

Compiled by BioPhotonics staff

A widely used method of monitoring protein changes in biophysical research could become a clinically useful tool sensitive enough to diagnose cataracts before significant damage, light scattering, aggregation and visual impairment occur.
Cataracts are the leading cause of blindness worldwide,...Read full article

Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...
